Description
上述のように、図４～図６に示される配置は傾斜させられた切り嵌め細工の半球形内への投影である。傾斜させられた切り嵌め細工は、逆メルカトル投影（inverse Mercator projection）または他のマップ投影を用いて半球形に変換することができる。したがって、アンテナアレイ６のその軸の周りの回転は、半波長基準を満たす有効間隔を伴う実質的に均一な密度を有する実際上のアレイを定めるように、アンテナ１６が、アンテナ１６の元の位置間の、間隔を空けられた新しい位置を占めるようにする。図７は、互いに重なる各々の配置のアンテナ１６の位置を示し、それ故に、実際上のアレイの密度を示す。 As mentioned above, the arrangements shown in FIGS. 4-6 are projections of the beveled inset work into a hemisphere. Inclined incisions can be transformed into a hemisphere using inverse Mercator projection or other map projections. Thus, the antenna 16 is in its original position with the antenna 16 so that rotation around its axis of the antenna array 6 defines a practical array with a substantially uniform density with effective spacing that meets the half-wave reference. Try to occupy a new, spaced position in between. FIG. 7 shows the location of the antennas 16 in each arrangement that overlaps each other and therefore shows the density of the actual array.
